You can add suite=IOP to the l2gen command as in
I think the default is iop_opt=7, but iop_opt=3 should work too

We do provide cloud mask with Level 2 data. The gray area is cloud/ice. See the attached

Use Rrs_nnn instead of Rrs_vvv as in "Kd_490 Rrs_nnn angstrom aot_865 chlor_a" for l2prod in the Selected Products tab.
